Building a helloworld like extension or say numpy.core is kind of the
same from a build point of view. The problem really is to work in many
different configurations (for example supporting building python
extensions for a different python than the one running scons), on
Waf (a project which started as a fork of scons and is now a totally
different project for all purpose) has a python tool, and it is 300
lines of code:
And it has more support for this kind of things than scons. My current
work for a python extension for scons is ~ 200 lines, not including unit
